Be it known that IJVINSLOW L. FAY, a citizen of the United States,residing at Elyria, in the county of Lorain and State of Ohio, haveinvented a new and useful Recoil-Spring for Baby-Carriages, of whichthefollowing is a specification.

My invention relates to improvements in springs for baby-carriages, inwhich the spring operates in conjunction with one 'or more wheels of thecarriage; and the objects of my improvement are, first, to provide arecoilspring so constructed that it can be easily connected with ordisconnected from one or more wheels of a baby-carriage, and, second,such spring so constructed that when connected with said wheel and thecarriage pushed in one direction it will increase the tension of saidspring until the carriage is stopped,when the force of the springoperating on the wheel will revolve it in the opposite direction, and bythe traction of the wheel return the carriage back to its startingpoint. I attain these objects by means of the mechanism illustrated inthe accompanying drawings, in which Figure I is a side elevation of myinvention applied to the broken sections of an axle and hub of the wheelof a baby-carriage. Fig. II is a side elevation of the faceplate of myinvention with core attached. Fig. III is a plan view of Fig. II. Fig.IV is a plan view of the barrel or shield covering the spring. Fig. V isa view of a coiled spiral spring. Fig. VI is a plan view of a click orpawl used. Fig. VII is a plan view of ratchet attached to hub of wheel.

Similar letters refer to similar parts throughout the several views.

A represents the broken section of the axle to an ordinarybaby-carriage.

13 represents the section of the side rail connecting the back and frontaxles.

O represents the broken section of the hub of a wheel to ababy-carriage.

(t represents a barrel or shield, the inner end of which is closedexcept in the center, where it is provided with a square hole a. ofsufficicnt size to fit the axle A and not permit of said barrel turning.It is also provided with a small hole a, of sufficient size to receiveone end of a spring. The front or outside end of the shield 01' barrelis entirely it, which turns freely in the hole 71. in the face-plate Z).To this pin it may be attached a lever e, which can be used as a handleto throw the click or pawl in or out of connection with the ratchet.

l) is a core or cylinder attached to the faceplate rigidly, over andaround which the spiral spring winds or turns. This core is ofsufficient length to reach the bottom of the shield or barrel a, and ofsuch diameter as to allow sufficient room between it and the inside ofthe barrel a for the spiral spring 3 to work freely. 1)" represents around hole in this faceplate of sufficient size to allow it to turn onthe axle A freely.

1/ represents a small hole of suflicient size to receive one end of thespring S.

S represents a spiral coiled spring of sufficient size and length to fitinside the barrel or shield a. Its two ends are turned out at rightangles and one end inserted through the hole a and the other through thehole 1/.

R represents a ratchet with a hole 1 in its center, of sufficient sizeto pass over the shoulder on the axle to a baby-carriage, and it isprovided with the screw-holes n n, for securing same to the hub of theWheel.

Having fully described the construction and parts of my invention asillustrated, it is put together and operated as follows, to wit: Thespring S is placed inside the barrel a,with one end passing through thehole a". The face-plate Z) is then placed over the uncovered end of thebarrel a,with the core 1) inside the spring S, and the other end of thespring S is passed through the hole b. The pin h,with. click or pawl,and lever c are next attached and the whole placed on the axle, thesquare hole (1/ preventing the barrel to from turning and the round holeI) permitting the faceplate I) to turn freely. The plate 12 is placed vWhat I claim as new, and desire to obtain on the-'aX'le;'-so[the' partto which thepawl or "by"Letters"Patent of the'United"States, is click isattached will stand uppermost.
